Dr. Yukio Ohtsuki realized excellent performance characteristics through the development of over-sized motorcycles, and furthered Kawasaki’s reputation after switching from two- to four-cycle engines to comply with exhaust gas emission regulations. He also achieved a great deal in the research of gas turbines. In recognition of these great achievements, the Japan Automotive Hall of Fame is honored to induct Dr. Yukio Ohtsuki into the Hall of Fame.

Ohtsuki was instrumental in the development of the 900 Z1 (seen here in T-103 prototype guise). It was Japan’s largest bike at the time, and also spawned the 750cc domestic model Z2.

The Mach range covered 250 to 750cc models, and revitalized Kawasaki’s image.
